ATMEL Atmel AVR micro controller ATmega32M1 handbook

This chip is a high performance, low power AVR® 8-bit microcontroller with up to 1 MIPS throughput per MHz, with a built-in 12-bit high speed PSC (Power Stage Controller) that provides non-overlapping inverted PWM output pins with flexible dead-time, variable PWM duty cycle and frequency, and synchronous update of all PWM registers
